This is my favourite film of all time. Cary Grant and Katherine Hepburn gel in such a superb way that from beginning to end the film is a delight and very funny. When it comes to screwball comedies then this is the one that all others should be measured against. Grants playing of the hapless Professor in pursuit of a grant for his museum is masterful. Hepburn matches him step for step as the rich heiress who falls for him and will do almost anything to keep him near her. The scene in the hotel when Hepburn looses the bottom of her dress and Grant walks step for step behind her to cover the embarrassment is priceless. The film is a joy and always cheers me up when I watch it. Everyone who likes comedy should buy a copy of this and encourage everyone they know to watch it. I can give it no higher praise.
